Lipid-rich enteral nutrition regulates mucosal mast cell activation via the vagal anti-inflammatory reflex.

Nutritional stimulation of the cholecystokinin-1 receptor (CCK-1R) and nicotinic acetylcholine receptor (nAChR)-mediated vagal reflex was shown to reduce inflammation and preserve intestinal integrity. Mast cells are important early effectors of the innate immune response; therefore modulation of mucosal mast cells is a potential therapeutic target to control the acute inflammatory response in the intestine. The present study investigates intestinal mast cell responsiveness upon nutritional activation of the vagal anti-inflammatory reflex during acute inflammation.

Scheduled feeding results in adipogenesis and increased acylated ghrelin.

Ghrelin, known to stimulate adipogenesis, displays an endogenous secretory rhythmicity closely related to meal patterns. Therefore, a chronic imposed feeding schedule might induce modified ghrelin levels and consequently adiposity. Growing Wistar rats were schedule-fed by imposing a particular fixed feeding schedule of 3 meals/day without caloric restriction compared with total daily control intake.

Cholecystokinin/Cholecystokinin-1 receptor-mediated peripheral activation of the afferent vagus by enteral nutrients attenuates inflammation in rats.

Objective: The current study investigates activation of the nutritional anti-inflammatory pathway by lipid-rich nutrition.

Background: Enteral nutrition activates humoral and neural pathways to regulate food intake and sustain energy balance. Recently, we demonstrated that enteral nutrition and in particular lipid-rich nutrition modulates inflammation and prevents organ damage.

Biodistribution and pharmacokinetics of PEG-10kDa-cholecystokinin-10 in rats after different routes of administration.

Cholecystokinin, produced in the proximal small intestine, is a short acting satiating peptide hormone. CCK-10, before and after mono-iodination, was previously coupled to 10kDa polyethylene glycol (PEG). The formed conjugates PEG10kDa-CCK-10 and PEG10kDa-[(127)I]-CCK-10 show after i.

Effect of macronutrient ratio of the pre-starter diet on broiler performance and intermediary metabolism.

The aim of this study was to investigate the influence of isoenergetic substitution between the three energy delivering macronutrients in pre-starter diets on performance and intermediary nutrient metabolism in broiler chickens. From hatch until 5 days of age, 600 chicks, collected during peak of hatch, were fed one of the three experimental pre-starter diets with isoenergetic (13 MJ metabolisable energy/kg) substitutions between fat (43 vs. 108 g/kg), protein (126 vs.
